' a GAS-BURNER.

Be it known that 'I, SIMEON F. Pmnon', a citizen of the United. States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Gas-Burners, of which the following is a specification..

My invention relates to improvements 1n incandescent gas burners, its object being particularly to provide means for more thoroughlymixing the air and. gas than in the ordinary burner,

"and vincooperation. there; with improved pilot light means, the tea tures of construction of thelburneribeing. such as to cooperate in stabil zing the flow I of gas to. the mantle and at the same time protect the pilot light.

To this end the invention consistsinfthe features of construction, combination, and arrangement of parts hereinafter described andclaimed. I I

In the accompanying drawings. form ng"; part of this specification, I I I Figure 1 is an elevation and section of the burner and supported-mantle;

-Fig. 5 is an elevation of a post supported street lamp. embodying my features of inven t L tion and'provided with an auxiliary lighter for the mantle; and

- .charge or'nozzle member 2. The

Fig. 6 is" a sectional elevation taken at right angles to Fig. 5. iReferring: to the drawings, A represents a gas inlet tube threaded into the gas d1s-.

is formed with a'transverse opening 3 into whiohis'fitted the rotatable valve, 4, said valve'carrying an arm 5 on its outerjend to which isdetachably connected an actuating rod 6, said rod being slidable in a bracket 7 I on the post 8, and being adapted to ;.be held inadjusted positions by a suitable "screw 9.

valve is formed with a transverse .middle I opening 11 adapted; when the valve is turned into the position shown in Fig; 45 to bring) thev inlet openinglQ into, communication with the outlet'openings: 1'3 andsie In the 1 upper ends of'the outlet openings 13am nerthefmantle 28;

The tube 29 is also formed with openings '34 adjacent to' its lower end."

In Fig. 2 is shown'the tures adapted for use with a depending above describedifeamantle, In the adaptation shown in Fig.22

To use asan auXili-arypilot light to lightthe 1 mantle in case the pilot light happenstoi-be out, I provide a. tube a l -i supported; in a; bracket 42 alongside the gas inletpsaid tube 41 being connected by a conduit 43 Withrthe" groove 40 around the valve. The tube 41 extends' below the bottom .ofi'the lampz casing; 442, as shown in Fig. 5, and is rotatable Within the bracket so as to be'turnedinto"orout of communication With the g as containing, groovedO; The tube dlis prov'idedwith' side openings 45- both belowthe lamp and alongside the mantle.
